Med-El BoneBridge and Med-El Vibrant Soundbridge
The Med-El BoneBridge is another type of bone-anchored auditory processor system that may be used in patients with microtia and atresia. The BoneBridge is the world’s first active bone conduction implant. This bone conduction implant enables sound transmission directly to the inner ear by means of bone conduction. The BoneBridge is a semi-implantable hearing system, in which the implant is positioned completely under the skin. The implant receives the signals from an external audio processor which is worn under the hair.
The BoneBridge system consists of:
Active Bone Conduction Implant

The Vibrant Soundbridge system consists of:
Implant and Floating Mass Transducer
The Vibrant Soundbridge is a middle ear implant system that is another alternative for patients with microtia and atresia. The Soundbridge is an alternative to conventional hearing aids or bone conduction devices. This device consists of an externally worn audio processor and an implant which is surgically placed under the skin. The audio processor is held in place by magnetic energy and can be worn under or over the hair. Sounds are picked up by the microphone in the audio processor. The audio processor converts these sounds into electrical signals. The electrical signals are transmitted through the skin to the implant. The implant relays the signal down a conductor link to the floating mass transducer. The floating mass transducer converts signals into mechanical vibrations which set the structures of the middle ear into motion. The motion of the middle ear structures then send the vibration directly to the inner ear hearing organ.
